Consider xastir on a Linux workstation or running in a Linux VM, with a
feed from aprs-is, filtered for wx stations only. It'll present the
station symbols, optionally with current wx stats in the label, and the
full wx telemetry is just a right-click away.
However, among the many map formats that xastir supports, google maps is
not among them. The Census bureau's Tigermap data is probably the most
accessable, and with the WMSRADAR as an overlay, makes for a very
impressive display. And the other shortcoming is that the individual
stations' wx data is displayed as current-only, with no historical info
kept, or graphical trend possible.
If you're bent on developing something yourself, I'd encourage you to
leverage the incredible work the xastir developers have done already, and
develop an add-on to xastir that would create and display in
near-real-time an isobar and/or isotherm map layer from the incoming wx
data, which could be overlayed on the already-beautiful maps that xastir
Come to think of it, it doesn't have to be built-in to xastir at all.
Build it as a stand-alone map server, akin to the TIGERMAP.GEO or
WMSRADAR.GEO services I mentioned earlier, and put it up where we can all
take advantage of it!
